일반적으로 전해란 전기분해를 의미하는 것으로, 이러한 전기분해는 전해액에 전류를 가함으로써, 전해액에 포함된 이온들이 음극 또는 양극으로 이동하는 현상을 의미한다. 이러한 전기 화학적 반응에 의해 음극 또는 양극에서는 가스가 발생하거나, 금속 이온이 환원되어 금속이 석출되는 등의 현상을 일으켜, 산업분야에서 다양하게 이용되고 있다. 특히 이러한 전해 공정을 통해 순도 높은 금속 물질을 제조하는 공정이 다수 이용되고 있으며, 전해 공정을 통해 생산되는 금속들은 구리, 니켈, 아연, 코발트, 납, 백금, 이리듐, 루테늄, 팔라듐, 금 및 은 뿐만 아니라 다수의 전이금속이 전해 제련 또는 전해 정련 공정을 통해 생산될 수 있다. In general, electrolysis refers to electrolysis, and this electrolysis means a phenomenon in which ions included in the electrolyte move to the cathode or the anode by applying an electric current to the electrolyte. Such an electrochemical reaction causes a phenomenon in which a gas is generated in the cathode or the anode, or metal ions are reduced to precipitate a metal, and thus are widely used in industrial fields. In particular, many processes for producing highly pure metallic materials through such electrolytic processes are used, and the metals produced through electrolytic processes include copper, nickel, zinc, cobalt, lead, platinum, iridium, ruthenium, palladium, gold, and silver. In addition, many transition metals may be produced through electrolytic smelting or electrorefining processes.
이러한 전해 제련은 여러 가지 방법이 있으나, 통상적으로 전해액이 수용된 전해조 내에서 수행되며, 여러 개의 양극판 및 음극판을 설치하여 수행되는 것이 통상적이다. 이러한 전해 제련에 이용되는 양극판은 아연, 구리 및 카드뮴 등이 있으며, 이러한 물질들은 상대적으로 전기 전도도가 높으며 비교적 화학적으로 안정하여 전해 제련용 양극에 다수 이용되고 있다. 그러나, 전해 제련의 특성상 산성 환경이며, 전기, 화학적 반응이 동시에 수반되는 공정 특성상 비교적 화학적으로 안정하다 하더라도 일부 양극판의 금속 물질이 용출될 수 있으며, 용출된 양극판의 금속 물질은 생산하고자 하는 금속에 불순물로 포함될 수 있는 문제점이 있다.There are many methods for such electrolytic smelting, but is usually performed in an electrolytic cell containing an electrolyte solution, and is usually performed by installing a plurality of positive electrode plates and negative electrode plates. The positive electrode plates used for electrolytic smelting include zinc, copper, and cadmium. These materials are relatively high in electrical conductivity and relatively chemically stable, and thus are widely used in the positive electrode for electrolytic smelting. However, even though it is an acidic environment due to electrolytic smelting and is relatively chemically stable due to process characteristics involving both electrical and chemical reactions, the metal material of some of the positive electrode plates may be eluted, and the metal material of the eluted positive electrode plates is impurity in the metal to be produced. There is a problem that can be included.

본 발명에 의한 전해 제련용 양극 구조체를 이용하여 금속 제련 공정을 수행하는 경우, 모재 상에 형성된 금속 코팅층에 의해 모재의 용출을 방지할 수 있으며, 이러한 모재의 용출 방지에 의해 전해 제련에 의해 제조되는 금속의 순도를 더욱 향상시킬 수 있는 장점이 있다. 나아가, 모재를 금속 코팅층이 보호함으로써 종래 사용되던 양극판 대비 오랜 기간 사용함으로써 전해 제련 장치의 유지비용을 현저히 줄일 수 있는 장점이 있다.When performing a metal smelting process using the electrolytic smelting positive electrode structure according to the present invention, it is possible to prevent the dissolution of the base material by the metal coating layer formed on the base material, it is produced by electrolytic smelting by preventing the dissolution of the base material There is an advantage that can further improve the purity of the metal. Furthermore, since the base metal is protected by the metal coating layer, there is an advantage that the maintenance cost of the electrolytic smelting device can be significantly reduced by using the base material for a long time compared with the conventionally used positive electrode plate.
본 발명의 일 실시예에 의한 전해 제련용 양극 구조체는 모재 상에 형성된 금속 코팅층을 포함하며, 이러한 금속 코팅층은 티타늄(Ti), 루테늄(Ru), 이리듐(Ir), 백금(Pt), 망간(Mn) 및 탄탈럼(Ta)에서 선택되는 하나 또는 둘 이상을 포함할 수 있다. 이때 하나 또는 둘 이상을 포함한다 함은 티타늄(Ti), 루테늄(Ru), 이리듐, 백금, 망간 및 탄탈럼은 단일 물질로 금속 코팅층을 형성하거나, 이들 중에서 선택되는 하나 또는 둘 이상이 단순히 혼합된 혼합물이거나, 이들 금속에 의해 형성된 합금일 수 있음을 의미한다. 상술한 바와 같이 티타늄, 루테늄, 이리듐, 백금, 망간 및 탄탈럼에서 선택되는 하나 또는 둘 이상의 금속이 모재 상에 코팅층을 형성하는 경우, 코팅층에 의해 모재의 유출을 방지함으로써 제조되는 금속의 순도를 높일 수 있을 뿐만 아니라, 상기 금속 코팅층에 포함되는 금속의 전기 전도도가 상대적으로 높아 전극의 통전률을 높임으로써 전해 제련에 필요한 전압을 낮출 수 있고, 결과적으로 전해 제련에 소비되는 전력을 현저히 감소시킬 수 있는 장점이 있다. Electrolytic smelting positive electrode structure according to an embodiment of the present invention includes a metal coating layer formed on the base material, the metal coating layer is titanium (Ti), ruthenium (Ru), iridium (Ir), platinum (Pt), manganese ( Mn) and tantalum Ta may be included. In this case, one or more than one includes titanium (Ti), ruthenium (Ru), iridium, platinum, manganese, and tantalum to form a metal coating layer with a single material, or one or two or more selected from these are simply mixed. It may be a mixture or an alloy formed by these metals. As described above, when one or two or more metals selected from titanium, ruthenium, iridium, platinum, manganese and tantalum form a coating layer on the base material, the purity of the metal manufactured by preventing leakage of the base material by the coating layer is increased. In addition, the electrical conductivity of the metal included in the metal coating layer is relatively high, thereby increasing the current conduction rate of the electrode, thereby lowering the voltage required for electrolytic smelting, and consequently significantly reducing the power consumed in electrolytic smelting. There is an advantage.
더욱 좋게는, 본 발명의 일 실시예에 의한 금속 코팅층은 루테늄, 탄탈럼, 이리듐, 망간 및 티타늄에서 선택되는 하나 이상을 포함할 수 있다. 본 발명의 일 실시예에 의한 금속 코팅층이 루테늄, 탄탈럼, 이리듐, 망간 및 티타늄에서 선택되는 하나 이상을 포함하는 경우, 소요전력의 저감효과가 더욱 우수하며, 제련공정의 수율을 90% 이상으로 향상시킬 수 있는 장점이 있다. More preferably, the metal coating layer according to one embodiment of the present invention may include one or more selected from ruthenium, tantalum, iridium, manganese and titanium. When the metal coating layer according to an embodiment of the present invention includes at least one selected from ruthenium, tantalum, iridium, manganese and titanium, the effect of reducing power consumption is more excellent, and the yield of the smelting process is 90% or more. There is an advantage that can be improved.
나아가, 본 발명의 일 실시예에 의한 금속 코팅층은 루테늄, 탄탈럼 및 이리듐에서 선택되는 하나 이상의 제 1 금속 및 망간 및 티타늄에서 선택되는 하나 이상의 제 2 금속이 혼합된 상태일 수 있으며, 이러한 제 2 금속의 혼합으로 금속 코팅층의 결착력을 향상시키고 제 1 금속의 소실을 방지할 수 있는 장점이 있다. 이때 첨가되는 제 2 금속은 전체 금속 코팅층 중 10 내지 50 중량% 더욱 구체적으로는 20 내지 40 중량%일 수 있다. Furthermore, the metal coating layer according to an embodiment of the present invention may be in a state in which at least one first metal selected from ruthenium, tantalum, and iridium and at least one second metal selected from manganese and titanium are mixed. The mixing of the metals has the advantage of improving the binding strength of the metal coating layer and preventing the loss of the first metal. In this case, the added second metal may be 10 to 50% by weight of the total metal coating layer, more specifically 20 to 40% by weight.
구체적으로, 상기 금속 코팅층의 두께는 전해 제련에 의해 생산하고자 하는 금속의 종류 및 전해 제련 장치의 운전 환경에 따라 달라질 수 있으나, 구체적으로 0.5 내지 50 ㎛, 바람직하게는 0.5 내지 20 ㎛일 수 있다. 상기 범위에서 과도한 두께의 금속 코팅층을 필요로 하지 않으면서도 모재를 보호할 수 있는 장점이 있다. Specifically, the thickness of the metal coating layer may vary depending on the type of metal to be produced by electrolytic smelting and the operating environment of the electrolytic smelting apparatus. Specifically, the thickness of the metal coating layer may be 0.5 to 50 μm, preferably 0.5 to 20 μm. In the above range there is an advantage that can protect the base material without requiring a metal coating layer of excessive thickness.
본 발명의 일 실시예에 의한 전해 제련용 양극판에서 상기 모재는 통상적으로 전해 제련용으로 이용될 수 있는 통전 가능한 금속인 경우 제한이 없으나, 구체적으로 납, 티타늄, 니켈, 구리 및 망간에서 선택되는 하나 또는 둘 이상일 수 있다. 아울러, 이러한 모재의 형상은 전해 제련 효율을 확보할 수 있는 형상인 경우 제한이 없다. 구체적이고 비한정적인 일예로 상기 모재는 판형, 타공을 포함하는 판형, 메시망 형태, 절곡된 형태일 수 있으나 본 발명이 이에 제한되는 것은 아니다. 나아가, 상기 금속 코팅층을 포함하는 전극 역시 모재와 동일한 형상일 수 있다. 이러한 모재는 전극 상에 고르게 전류를 공급하면서도, 전해 제련 효율을 확보할 수 있는 범위인 경우 제한이 없으나 구체적으로 두께가 0.1 내지 10 ㎜, 더욱 구체적으로는 0.5 내지 5 ㎜일 수 있다. 상기 범위에서 전류를 효율적으로 전달하여 전해 제련 효율을 확보할 수 있다. 이에 더하여, 본 발명의 일 실시예에 의한 판형 전극의 넓이는 목적하는 금속의 종류, 공급되는 전류 및 전압의 세기에 의해 달라질 수 있다. 구체적이고 비한정적인 일 예로 상기 전극의 넓이는 1 내지 4 m2, 더욱 구체적으로는 2 내지 3 m2일 수 있으나 본 발명이 이에 제한되는 것은 아니다. In the positive electrode plate for electrolytic smelting according to an embodiment of the present invention, the base material is not particularly limited in the case of an electrically conductive metal that can be used for electrolytic smelting, but specifically one selected from lead, titanium, nickel, copper and manganese. Or two or more. In addition, the shape of such a base material is not limited in the case of a shape that can ensure the electrolytic smelting efficiency. In one specific and non-limiting example, the base material may be a plate shape, a plate shape including perforations, a mesh network shape, or a bent shape, but the present invention is not limited thereto. Further, the electrode including the metal coating layer may also have the same shape as the base material. Such a base material is not limited in the case of supplying a current evenly on the electrode, but in the range that can ensure the electrolytic smelting efficiency, specifically, the thickness may be 0.1 to 10 mm, more specifically 0.5 to 5 mm. The current can be efficiently delivered in the above range to ensure electrolytic smelting efficiency. In addition, the width of the plate-shaped electrode according to an embodiment of the present invention may vary depending on the type of metal desired, the current supplied and the strength of the voltage. As a specific and non-limiting example, the width of the electrode may be 1 to 4 m 2 , more specifically, 2 to 3 m 2 , but the present invention is not limited thereto.
나아가, 본 발명의 일 실시예에 의한 상기 모재는 표면 요철을 포함할 수 있으며, 이러한 표면 요철에 의해 모재와 금속 코팅층간의 높은 결착력을 나타낼 수 있는 장점이 있다. 구체적으로, 본 발명의 일 실시예에 의한 상기 모재표면에 형성된 요철은 표면 조도(Ra)가 0.1 내지 100 ㎛, 구체적으로는 1 내지 60 ㎛, 더욱 구체적으로는 10 내지 40 ㎛일 수 있다. 모재 표면에 형성된 요철이 상기 범위를 만족하는 경우, 모재와 금속 코팅층의 결착력을 더욱 향상시킴으로써 장기간 사용에 의한 코팅층의 이탈과 같은 문제점을 예방할 수 있는 장점이 있다. 나아가, 전해 제련 공정의 수행 시 발생할 수 있는 온도 변화에 의한 팽창 및 수축의 반복에도 높은 결착력을 나타내어, 열팽창계수 차이에 의한 크랙 등의 발생을 예방할 수 있으며, 결과적으로 본 발명의 일 실시예에 의해 제조된 전해 제련용 양극판을 오랜 기간 사용할 수 있는 장점이 있다. In addition, the base material according to an embodiment of the present invention may include surface irregularities, there is an advantage that can exhibit a high binding force between the base material and the metal coating layer by the surface irregularities. Specifically, the unevenness formed on the base material surface according to the embodiment of the present invention may have a surface roughness Ra of 0.1 to 100 μm, specifically 1 to 60 μm, and more specifically 10 to 40 μm. When the unevenness formed on the surface of the base material satisfies the above range, there is an advantage of preventing problems such as detachment of the coating layer by long term use by further improving the binding force between the base material and the metal coating layer. Furthermore, it exhibits high binding strength even after repeated expansion and contraction due to temperature changes that may occur during the electrolytic smelting process, thereby preventing occurrence of cracks due to thermal expansion coefficient differences, and as a result, according to an embodiment of the present invention. There is an advantage that the manufactured electrolytic smelting positive electrode plate can be used for a long time.
본 발명에 의한 전해 제련용 양극판은 상기 통전용 지지체와 결합된 헤드바를 포함한다. 이러한 헤드바는 전해 제련 공정의 수행 시 전해액과 직접 접촉하지 않고 외부에 노출되며, 이러한 헤드바를 통해 상기 전극에 전류를 공급함으로써 전해 제련 공정의 수행이 가능하다. The positive electrode plate for electrolytic smelting according to the present invention includes a head bar combined with the support for electricity delivery. The head bar is exposed to the outside without directly contacting the electrolyte during the electrolytic smelting process, it is possible to perform the electrolytic smelting process by supplying a current to the electrode through the head bar.
나아가, 본 발명의 일 실시예에 의한 상기 헤드바는 통전용 금속바(110) 및 상기 통전용 금속바 상에 형성된 금속바 피복층을 포함할 수 있다. 이러한 금속바 피복층을 통해, 통전용 헤드바의 손상을 예방할 수 있다. 구체적으로, 통상적인 전해 제련 공정은 황산 등의 산 조건에서 수행되는 경우가 많으며, 상기 헤드바가 산과 직접 접촉하지 않는다 하더라도 전해 제련 공정의 수행 중 황산 전해 제련용 전해액의 비산이 발생할 수 있으며, 이렇게 비산된 전해액에 의해 통전용 헤드바가 부식되는 등의 문제가 발생할 수 있다. 나아가 이러한 부식에 의해 헤드바가 일부 전해액에 유입될 수 있으며, 결과적으로 이는 최종적으로 생산되는 금속에 포함되어 불순물이 유입되는 문제가 발생할 수 있다. Furthermore, the head bar according to an embodiment of the present invention may include a metal bar covering layer formed on the metal bar 110 for electricity delivery and the metal bar for electricity delivery. Through such a metal bar coating layer, it is possible to prevent damage to the head bar for power transmission. Specifically, the conventional electrolytic smelting process is often carried out under acidic conditions such as sulfuric acid, even if the head bar does not directly contact the acid, the scattering of the electrolytic solution for sulfuric acid electrolytic smelting may occur during the electrolytic smelting process.

본 발명에 의한 전해 제련용 양극 구조체 제조방법을 통해 제조된 전해 제련용 양극 구조체는, 전극 상에 형성된 코팅층을 통해 장기간 사용이 가능하며, 종래 이용되던 전극판의 용출을 방지함으로써 금속의 전해 제련 공정에 이용 시 불순물함량을 현저히 낮추고 순도를 높일 수 있는 장점이 있다.

When one or two or more metals selected from titanium, ruthenium, iridium, platinum, manganese and tantalum form a coating layer on the base material, it is possible to increase the purity of the metal produced by preventing leakage of the base material by the coating layer. In addition, the electrical conductivity of the above-described metal is high, so that the current passivation rate can be increased to lower the voltage required for electrolytic smelting, and consequently, there is an advantage that the power consumed for electrolytic smelting can be significantly reduced.
더욱 좋게는, 본 발명의 일 실시예에 의한 금속 코팅층은 루테늄, 탄탈럼, 이리듐, 망간 및 티타늄에서 선택되는 하나 또는 둘 이상을 포함할 수 있으며, 본 발명의 일 실시예에 의한 금속 코팅층이 루테늄, 탄탈럼, 이리듐, 망간 및 티타늄에서 선택되는 하나 이상을 포함하는 경우 소요전력의 저감효과가 더욱 우수하며, 제련공정의 수율을 90% 이상으로 향상시킬 수 있는 장점이 있다. More preferably, the metal coating layer according to an embodiment of the present invention may include one or two or more selected from ruthenium, tantalum, iridium, manganese, and titanium, and the metal coating layer according to an embodiment of the present invention is ruthenium , Tantalum, iridium, manganese and titanium, when including one or more selected to reduce the power consumption is more excellent, there is an advantage to improve the yield of the smelting process to more than 90%.
좋게는, 본 발명의 일 실시예에 의한 금속 코팅층은 루테늄, 탄탈럼 및 이리듐에서 선택되는 하나 이상의 제 1 금속 및 망간 및 티타늄에서 선택되는 하나 이상의 제 2 금속이 혼합된 상태일 수 있으며, 이러한 제 2 금속의 혼합으로 금속 코팅층의 결착력을 향상시키고 제 1 금속의 소실을 방지할 수 있는 장점이 있다. 이때 첨가되는 제 2 금속은 전체 금속 코팅층 중 10 내지 50 중량% 더욱 구체적으로는 20 내지 40 중량%일 수 있다. Preferably, the metal coating layer according to an embodiment of the present invention may be a mixture of one or more first metals selected from ruthenium, tantalum and iridium and one or more second metals selected from manganese and titanium, The mixing of the two metals has the advantage of improving the binding strength of the metal coating layer and preventing the loss of the first metal. In this case, the added second metal may be 10 to 50% by weight of the total metal coating layer, more specifically 20 to 40% by weight.
나아가, 본 발명의 일 실시예에 의한 상기 전극 제조 단계는 Furthermore, the electrode manufacturing step according to an embodiment of the present invention
모재 표면에 요철을 형성하는 요철 형성 단계; 및 Irregularities forming step of forming the irregularities on the surface of the base material; And
상기 요철이 형성된 모재의 표면에 금속 코팅층을 형성하는 코팅 단계;를 포함하여 제조될 수 있다. It may be prepared, including; coating step of forming a metal coating layer on the surface of the base material on which the irregularities are formed.
상술한 바와 같이 모재 표면에 요철을 형성한 뒤, 이러한 요철 상에 금속 코팅층을 형성하는 경우, 모재와 금속 코팅층의 결착력을 강화할 수 있을 뿐만 아니라, 요철이 없는 경우 대비 금속 코팅층의 표면적이 넓어지게 되므로 보다 높은 통전률을 나타낼 수 있으며, 결과적으로 전해 제련에 필요한 전력소비를 줄일 수 있는 장점이 있다.As described above, when the uneven surface is formed on the surface of the base material, when the metal coating layer is formed on the uneven surface, not only the binding force between the base material and the metal coating layer can be strengthened, but also the surface area of the metal coating layer becomes wider than in the case where there is no unevenness. It can have a higher current carrying rate, and as a result, there is an advantage of reducing the power consumption required for electrolytic smelting.
이때, 상기 요철 형성 단계는 모재 상에 요철을 형성할 수 있는 방법인 경우 제한이 없으나, 연마 등과 같은 물리적인 방법을 이용하거나, 식각(etching)을 통해 요철을 형성할 수 있다. 이때 식각은 건식 식각 또는 습식 식각일 수 있으나, 이러한 요철 형성 단계는 모재의 종류 및 전해 제련에 의해 생산하고자 하는 금속의 종류에 따라 달라질 수 있으며, 본 발명이 이에 제한되는 것은 아니다.

In this case, the unevenness formed by the unevenness forming step may have a surface roughness Ra of 0.1 to 100 μm, specifically 1 to 60 μm, and more specifically 10 to 40 μm. In the case of forming the irregularities satisfying the surface roughness on the surface of the base material, there is an advantage that can prevent problems such as cracks or detachment of the coating layer by long-term use by further improving the binding force between the base material and the metal coating layer. In addition, it exhibits a high binding force even after repeated expansion and contraction due to temperature change that may occur during the electrolytic smelting process, there is an advantage that can be used for a long time the electrolytic smelting positive electrode plate manufactured by an embodiment of the present invention.

In addition, the method for manufacturing an anode structure for electrolytic smelting according to an embodiment of the present invention may include a coating step of forming a metal coating layer on the surface of the base material on which the unevenness is formed. This coating step is not limited when the method of forming one or more metal coating layers selected from the above-described titanium, ruthenium, iridium, platinum, manganese and tantalum on the base material. As a specific and non-limiting example, the metal coating layer may be formed on the base material by a plating method such as electroless plating or electrolytic plating, brushing, dipping or spraying, but the present invention is not limited thereto.
나아가, 이러한 금속 코팅층의 두께는 전해 제련에 의해 생산하고자 하는 금속의 종류 및 전해 제련 장치의 운전 환경에 따라 달라질 수 있으나, 구체적으로 0.5 내지 50 ㎛, 바람직하게는 0.5 내지 20 ㎛일 수 있다. 상기 범위에서 과도한 두께의 금속 코팅층을 필요로 하지 않으면서도 모재를 보호할 수 있는 장점이 있다. Further, the thickness of the metal coating layer may vary depending on the type of metal to be produced by electrolytic smelting and the operating environment of the electrolytic smelting apparatus, but may be specifically 0.5 to 50 μm, preferably 0.5 to 20 μm. In the above range there is an advantage that can protect the base material without requiring a metal coating layer of excessive thickness.
